Introducing The Revolutionary Resistance Spot Rivet™

Thank you for joining our mailing list.

Solving the challenge of joining dissimilar materials

Responding to the growing industry trend towards multi-material part design, Arconic Technical Center, in conjunction with Arconic Fastening Systems, has developed an advanced new technology, Resistance Spot Rivet™ (RSR™). This technology will effectively allow a wide range of dissimilar materials to be joined quickly and reliably, including:

RSR™ Advantages

This breakthrough technology offers a number of advantages, separating it from a wide range of conventional joining processes:

Joins UHSS and aluminium, steel to magnesium, and steel to composites

Joins 7000 series aluminium alloys to 6000 series and 5000 series aluminium alloys with higher joint strength than traditional resistance spot welding, all while using steel spot welding equipment and power input, for significant energy savings over typical aluminium spot welding

Can be installed using existing resistance spot welding equipment with our add-on feed system

Increases the flexibility of current joining infrastructure by enabling spot welding of similar materials in sequence with dissimilar material joining using resistance spot welding equipment

The installed rivet offers no rear protrusion
